If you have installed radiator insulation, don't forget about it when you get stuck: there's a sudden thaw outside (This has been happening quite often lately) or spring has come, otherwise the engine can overheat even if the electric fan of the cooling system is in good working order.
Be sure to carry a shovel with you. To combat deep snow (if he can meet you on your way) A special snow-removing or shovel shovel is best suited. For harder packed or melted snow and for digging out a car stuck in a rut, a regular bayonet shovel with a shortened handle for compactness is suitable.
If you regularly have to overcome slippery slopes, it is useful to carry a bag in the trunk (small bag) with coarse sand, brick chips or something similar. Often it is enough to throw a couple of shovels of this mixture under each wheel to get moving and overcome a steep icy slope or not to slide off the road, damaging the body.
